Title: Control for heat transfer system - has pump controlled in two stages by two thermostats
Inventor: SONNLEITNER ENGELBERT ING
IPC: G05D23/275
Filed: 1974-08-27
Abstract: The pump circulates water through a heating or cooling system and is supplied electrically from terminals. The first thermostat closes a switch which energises the pump through a resistance. The second thermostat closes a switch which short circuits the resistance thus increasing the potential applied to the pump and therefore the pump speed and flow of liquid. The two thermostats are set to operate in sequence on rise or fall of the controlled temp. and therefore produce a two step control of fluid flow and heat transfer although the thermostats themselves are commercially available on/off types. Further adjustment can be obtained by the use of a variable resistance.

Title: Extrusion of metallic workpieces - in which the blank is punched from the starting material and immediately extruded in the same work cycle
Inventor: BOLLMANN FRANZ
IPC: B21C25/00
Filed: 1975-05-21
Abstract: A process for extrusion of metallic workpieces, in particular of metallic flanges with high tube necks, in which a circular shaped blank is formed in a die by means of a hollow punch and a mandrel through backwards extrusion and the mandrel is driven through the flowing material against the effective direction of the hollow punch as previously claimed is designed so that the blank is first punched out of the flat material and immediately followed by back extrusion in the same working stage. The outer diameter of the blank can be chosen to correspond to the inside diameter of the dia. Equipment for the process comprises a die, a hollow punch and a mandrel guided loosely in a hole situated in the base of the die, in which the outer diameter of the hollow punch and the inside diameter of the die opening nearly correspond and both have sharp edges as with a blanking tool. The process is economical in avoiding a separate stage for blanking and if the outside diameter of the blank is the same as the inside diameter of the die, flow of material in the opposite direction to the extrusion direction is avoided.
